SELF-ACTING CHEESE-PRESS.

' Specification? of Letters Patent No.. 2,747, datedlAugustG, 184:2;A

To all whom t may concern.'

Be it known that we, CHESTER STONE, of Rootstown, in Portage county and State of Ohio,and FITCH` K. COLLINS and Griso.V S. COLLINS, of Ravenna, inV Portage county and State of Ohio, have invented a new and useful Machinefor Pressing Cheese, to be entitled the Buckeye Cheese-Press; and we` do hereby declare that the following is a full, clear, and exact description of the construction andoperation of the same, reference being had` tothe annexed drawings, making a part ofthis specification, of which Figure l is a perspective view andFig.` 2 a vertical section.

Our machine consists,first,ahorizontal sill or foot piece or base (A) being a piece of wood two inches thick four inches wide and two feet long with two horizontal transverse sills or cross pieces (a) (a) mortised and tenoned at the ends to prevent its turning and for rendering said base A steady and firm; second-a standing post (B) being a block of wood four inches square and one foot long to the shoulder having a tenon at the lower end set into the upper side of the aforesaid foot piece or base A; third-four parallel levers (c c c2 02) each one inch thick and three inches wide; two of them the upper ones 0 c being eighteen inches long and the other two c2 a2 siXteeninches. The long levers c2 c2 being united to each other by a horizontal transverse round or piece of wood y one inch in diameter and four inches long between the shoulders thereof having a tenon at each end one inch long which tenons are set into the levers connecting them firmly together near their centers. The short levers 0 c are firmly united by a round Z in like manner. These levers are connected to opposite sides of the standing post B by two pivots P passing `through the post and one end of the levers: the long lever c2 c2 being fastened opposite to each other siX inches above the foot piece; and the short levers opposite to each other and eleven inches above the foot piece five inches above the lower levers. Fourth-a falling post (D) being a vertical rising and falling block of wood four inches square and thirteen inches long. This post is connected with the levers at'the ends opposite to the standing-post by two pivots Q. The long levers being attached to the falling post by a pivot Q2 two inches above the lower end of this postl and 1 fifteen inches. from the lower pivot P2 in the standing post; the

short levers being connected to1thispost D by a pivot Qlseveninches above the lower end` ofthe post five;` inches above the `lower levers,` and" fifteen inches from` the upper pivot P* in the standing posti A mortise Rf is made inthe upper end` ofthe falling post; Dat right angles tothe levers and suiiicient to., permitthe beam E tomove in it without difficulty, ,andthrough the lower end` anothermortise Slis made also at right angles tothe levers sufiiciently large to admit the horizontal rod` V which passes through `the rising and falling uprights F F attached `t0 saidbeaniE to play freely'4 in said mortise S. Fifth*a beam or piece of wood (before referred to and lettered E) two inches square and two feet long, having a hole through each end to receive the two vert-ical screws H H which beam is placed in the mortise R in the upper end of the falling post D and at right angles to the levers. SiXtlr-two rising and falling uprights (F) (F) or pieces of wood one inch thick four inches wide and one foot long, having a mortise through their upper ends sufficient to receive the beam E to whicli they are made fast; being placed six inches lfrom each other and three inches on each side of the center of the beam, on opposite sides of the falling post and parallel to this post; having their lower ends connected to the ends of the lower levers by a horizontal transverse rod V passing through the uprights and ends of the levers; which rod is six inches and a half below the lower side of the beam E and one inch and a quarter from the lower pivot of the falling post and sixteen inches and a quarter outward from the lower pivot of the standing post and being in a direct line with these lower pivots P2 Q2 of the posts, B, D. Seventh-a form (G) or piece of plank twenty inches square and one inch and a half thick, secured from warping by battens (e) (e) crossing its lower surface; which form rests upon the upper end of the falling post D and is fastened to the same by a pin X passing through the battens and upper end of the post. Eighthtwo vertical screws (H) (H) rising from the ends of the beam being two feet long and one inch and a quar# ter in diameter, their lower ends being made fast to the beams which screws are furnished with two screw boxes or nuts (CZ) (d). Ninth-a follower or upper basin (I) being a bar of wood say four inches wide and two inches thick having a hole through each yend sufficient to receive the screws H H and which follower is forced down upon the cheese by the screw boxes or .nuts cl d above mentioned-said nuts being provided vwith handles for the convenence of turning them.

In using this press the falling post D is first raised ashigh as necessary by means of a hand lever (L) rested upon the top of the standing post as its fulcrum and bearing upon the lower side of the round (Z) which unites the upper levers near their center. The falling post is there made fast by a hook fastened to the outside of the standing post B and passing over the hand lever. The curd bein then placed upon the forrn Gr in a hoop y in the usual manner. The follower I is forced down upon the curd by means of the screw boxes d above its ends, thus giving a gentle pressure to the cheese at first; after which the hand lever is removed and the whole power of the levers of the press is left to act upon the cheese giving a greater or less pressure in proportion to the size of the cheese or the weight appended-the long levers 02 c2 causing the follower I placed upon the curd to descend more rapidly than the forms placed under it as said levers descend by means of the aforesaid arrangement-a contrary effect being produced in raising said levers-that is causing the follower to rise quicker than the form.

Y What we claim as our invention and desire to secure by Letters Patent is- The application of the power of the screw and falling` lever in a self acting press in manner as above described for the purpose of pressing cheese and other substances whether arranged precisely in the manner herein set forth or in any other mode substantially the saine.
